Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation equipment, and particularly relates to a fermentation tank convenient for the expansion culture of Bacillus coagulans. Background Art

[0002] Bacillus coagulans is a Gram-positive bacterium of the genus Bacillus. It can colonize in the intestine, reduce the intestinal pH, inhibit the growth of harmful bacteria, and play roles in regulating the intestinal health of animals, improving digestion ability and immunity. During the expansion culture of Bacillus coagulans, a fermentation tank is needed for its fermentation and expansion culture. Since the fermentation of Bacillus coagulans is an aerobic fermentation, the demand for dissolved oxygen is strict during the fermentation process. The authorized patent with the publication number CN216073816U discloses a fermentation tank for Bacillus coagulans, which includes a fermentation tank cover, a tank body, a feeding port, a discharging port, a stirring device, a sterilization / ventilation device, an electrode detection system, an antifoaming system, a feeding system, and an acid-base adjustment system. This patent fully improves the dissolved oxygen amount through the aspect ratio design, ensures the aerobic demand of the bacterial body fermentation, and reduces the energy consumption. However, the antifoaming agent of its antifoaming system is directly put into the fermentation tank and needs to be stirred to fully play its role, and the antifoaming teeth and the antifoaming agent act independently of each other, resulting in poor antifoaming effect and being unfavorable for fermentation production. Therefore, a fermentation tank convenient for the expansion culture of Bacillus coagulans is needed to solve the above technical problems. Summary of the Utility Model

[0019] The driving assembly includes a bevel gear one 15, a bevel gear two 16 and a stepper motor 17. The bevel gear one 15 is fixed on the stirring rod outside the fermenter body 1. The bevel gear two 16 meshes with the bevel gear one 15. The stepper motor 17 is connected with the bevel gear two 16, and the stepper motor 17 is fixed on the fermenter body 1;

[0020] The defoaming component includes a defoaming tube 9 with both ends sealed. The defoaming tube 9 is perpendicular to the stirring rod. A row of defoaming teeth 11 are evenly arranged on the lower surface of the defoaming tube 9. A liquid discharge hole 10 is arranged between two adjacent defoaming teeth 11. The liquid discharge hole 10 communicates with the defoaming tube 9. A liquid guide tube 8 is fixedly connected to the middle of the defoaming tube 9. A liquid storage tank 13 is fixed to the top inside the fermentation tank body 1. The liquid storage tank 13 is connected with a liquid inlet tube 12. The stirring rod passes through the liquid storage tank 13 and is rotatably connected to the liquid storage tank 13 through a bearing. An inlet liquid cavity is arranged inside the stirring rod. The inlet liquid cavity communicates with the liquid storage tank 13 through a first liquid inlet 19. The top of the liquid guide tube 8 extends into the inlet liquid cavity. A second liquid inlet 14 is arranged at the top of the liquid guide tube 8 located inside the inlet liquid cavity; the liquid guide tube guides the defoaming agent into the liquid storage tank, enters the inlet liquid cavity from the first liquid inlet, then enters the liquid guide tube from the second liquid inlet, enters the defoaming tube through the liquid guide tube and is discharged from the liquid discharge port.

[0021] The stirring rod includes an upper rod 6 and a lower rod 5. The upper rod 6 and the lower rod 5 are fixedly connected by two parallel connecting plates 7. A vertical moving channel 20 is formed between the two connecting plates 7. The inlet liquid cavity is located inside the upper rod 6. The defoaming tube 9 passes through the moving channel 20. The top end of the liquid guide tube 8 extends into the inlet liquid cavity and is connected with a vertical telescopic rod 18. The fixed end of the vertical telescopic rod 18 is fixed to the top end of the upper rod 6. The telescopic end of the vertical telescopic rod 18 extends into the inlet liquid cavity and is fixedly connected with the liquid guide tube 8. The vertical telescopic rod 18 is an electric push rod. The electric push rod is connected to an external power supply through a conductive slip ring. The setting here can drive the defoaming tube to move up and down along the moving channel through the expansion and contraction of the vertical telescopic rod, and defoam the foam at different heights. The defoaming range is improved. A liquid pump is arranged on the liquid inlet tube. A liquid level sensor is arranged at the top of the inlet liquid cavity. The liquid level sensor is electrically connected to the liquid pump.

[0022] A heating jacket 2 is arranged outside the fermentation tank body 1. A medium inlet and a medium outlet are arranged on the heating jacket 2.

[0023] The defoaming teeth 11 on the defoaming tube 9 on both sides of the moving channel 20 are staggered. With this setting, when the defoaming tube rotates with the stirring rod, the circular trajectory formed by the staggered defoaming teeth is tighter. The defoaming teeth on one side of the center of the defoaming tube are arranged corresponding to the liquid discharge holes on the other side of the center of the defoaming tube. When the defoaming tube rotates with the stirring rod, the defoaming agent discharged from the defoaming teeth and the corresponding liquid discharge holes can have a double defoaming effect on the foam in the same area, further improving the defoaming effect.

[0024] Working principle: Materials enter the fermentation tank body through the feeding port. Driven by the stepper motor, the stirring rod rotates to stir and mix the materials. During the fermentation process, when the foam generated rotates with the stirring rod in the defoaming pipe, the defoaming agent discharged from the defoaming teeth and drain holes defoams the foam. The defoaming agent can fully contact the foam and the materials, and cooperate with the defoaming teeth, improving the defoaming effect and efficiency, which is beneficial to fermentation production.

[0025] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments.
